VALVE.

SPECIFICATION forming part of Letters Patent No. 288,331, dated. November 13, 1883.

Application filed March 10, 1883. (No model.)

To all whom it may concern: 7

'Be it known that we, CHARLES S, HASKELL and WILLIAM B. FLEMING, of the city of Phila- (lelphia, State of Pennsylvania, have invented Y a new and useful Improvement in Valves, of

which the following is a full, true, and exact description, reference being had to the accompanying drawings. I

Our invention relates to an application of 'the auxiliary-valve principle to valves adapted to be opened and closed by hand or other mechanism; and it consists, generally, in so combining a secondary valve with the main valve as that the operation of 'said secondary valve will serve to close or to open or to open and close the main valve.

Our invention will be readily understood from the accompanying drawings, in which Figure 1 represents a cross-section of our valve, showing all the parts; Fig. 2, adetailed cross section of the valve itself; Fig. 3, a view of a modification; Fig. 4, a detailed view of the valve mechanism shown in Fig. 3.

Similar letters refer to similar parts in all" the drawings.

A represents the inlet-pipe and B the outlet-pipe. Our valve, as shown, is particularly applicable to a water-valve. 0 represents the main valve.

"We will describe first the valve shown in, Figs. 1 and 2. p

The main valve is pierced with ports D and and F, of which D communicates with the wa er-pressure and F withthe chamber above the main valve. Within the main valve is the auxiliary valve G, operated by the stem H. This auxiliary valve may be raised and lowered by turning the handle H. The lower part of the main valve has a pipe connecting with it and delivering through the outlet E to the atmosphere or waste. The main valve and itsconnections can move up and down vertically.

The operation of this valve can now be readily understood. In the position shown the water-pressure, entering by the pipe A, passes through the passage D past the auxil. iary valve, thence through the passage F into the chamber above the main valve, thereby seating the main valve firmly and closing the same. If the handle H be raised by unscrewing it, the opening 1) will be closed and the opening E will be opened. Therefore the water above the main valve 0 will flow downward and escape through the openings E, and the pressure acting beneath the main valve and in the annular space around will raise the same into the chamber above it. It will be observed that the upper part of the main valve is larger than the seating portion below.

It is obvious that in this and the otherfigures the valve should be suitably packedand provided with suitable seats, as is clearly shown in the drawings.

In Fig. 3 the valve is automatically closed, but is not automatically opened.

G represents the auxiliary valve. -The delivery from this valve is, however, directly into the outlet-pipe B through the hole K.

As shown in the drawings, the auxiliary valve being down, water passes through the port D t and port F into the chamber above the valve. thereby seating the same. As soon as the auxiliary valve G is raised the water will flow from the chamber above the main valve into the outlet, when the main valve can be readily raised by the handle H. y

We do not in this application claim, specifically, the inventions shown. in Figs. 2 and 5, intending to make separate applications therefor.

\Vhat we claim as our invention, and desire to secure by Letters Patent, is--- V 1. The combination of a main valve and an auxiliaryvalve independently operated and adapted to open and close the ports within the main valve, thereby causing the water-presstire to be alternately-admitted upon and allowed to escape from the chamber above said valve, substantially as described. f 2. The combination of a main valve connected to a piston, whichpiston is greater in area than the port of the main valve, and which piston carries an auxiliary valve, which auxiliary valve admits and allows the escape of water above said piston alternately, thereby opening and closing the main valve, substantially as described.
